Clojurians Log v2

postgresql pg-datahike 0.1 — PostgreSQL wire protocol + SQL translator for Datahike Datahike now speaks Postgres. Point any PG client (pgjdbc, psql, psycopg2, Hibernate, SQLAlchemy,) at a Datahike connection and it just works. Bidirectional at the datom layer — CREATE TABLE over pgwire transacts normal Datahike schemas + datoms; existing Datahike databases become SQL-queryable with zero setup; (d/q …) and SELECT * FROM person see the same rows. Four capabilities on top of plain SQL: • Multi-DB routing — jdbc:<db> picks the conn from a {name → conn} registry • Schema hints — : meta-attrs rename columns, hide attrs, mark FK targets on existing Datahike schemas • Temporal SET — SET _of = '2024-01-15' exposes d/as-of / d/since / d/history as session vars • Git-like branching — SELECT datahike.create_branch('feat', 'main') is O(1), no provisioning; SET datahike.branch = 'feat'; SET datahike.commit_id = '<uuid>' queries an exact historical commit (no other PG-compatible database offers that) Verified end-to-end: pgjdbc ResultSetTest 80/80, Hibernate DatahikeHibernateTest 13/13, SQLAlchemy 7-phase 16/16, Odoo 19 module boot + TestORM.
